[APX EGPR] Handle vex insns that only support GPR16 (5/5)

These vex insn may have legacy counterpart that could support EGPR,
but they do not have evex counterpart. Split out its vex part from
patterns and set the vex part to non-EGPR supported by adjusting
constraints and attr_gpr32.

insn list:
1. vmovmskpd/vmovmskps
2. vpmovmskb
3. vrsqrtss/vrsqrtps
4. vrcpss/vrcpps
5. vhaddpd/vhaddps, vhsubpd/vhsubps
6. vldmxcsr/vstmxcsr
7. vaddsubpd/vaddsubps
8. vlddqu
9. vtestps/vtestpd
10. vmaskmovps/vmaskmovpd, vpmaskmovd/vpmaskmovq
11. vperm2f128/vperm2i128
12. vinserti128/vinsertf128
13. vbroadcasti128/vbroadcastf128
14. vcmppd/vcmpps, vcmpss/vcmpsd
15. vgatherdps/vgatherqps, vgatherdpd/vgatherqpd
